Olympus Statement About Fourthirds and Micro Fourthirds

I'd respectfully submit that your definition of what constitutes "mature" camera, whatever it is, will probably look different to someone with different subject and style of shooting. A photographer for whom, according to his shooting habits and needs, stronger points of E-5 and a system as a whole matter more while sensor capabilities cover his IQ needs (with clear promise of further improvement coming soon) will consider it more "mature."
